In addition to. providing for t'heLpas'sage 4v0f ',therstems .30,*Qthe openingsl lihprovide' com'- munication `between the suctionl passage .24 andthe chamber .-12 and betWeenJthe/pressure relief ports 2 5 ,and Said chamber.

extending from opposite sides `offrsaid plug are arms 32. e These arms have n their. outer Yends,.connected by members33 which are providedjvith sockets` 34, the latter receivs ing the outer ends .of the stems 30. These members 33 are pivotally .connected to 'hails or loops 35 which are in turn pivote-ily mounted in the outer ends of arms 36. These last mentioned arms extend diametrically from the upper end of a sleeve 37 which is slidingly mounted upon the hollow guide post 21. The out-er end of the sleeve 37 is provided with a radially disposed stop flange :38.

Mounted for sliding movement upon the sleeve 37 is a ioat 39 which is adapted to engage the arms 36 and the flange 38.

Communication between the Chambers 12 and 13 may be established through a passage 39 which is controlled by ,a vacuum conn trolled valve 40.

Located within .the chamber 13 is a container .or receiving chamber 41. This chamber yis located directly beneath the outlet end of the passage 39 and is provided with a plurality of spaced filtering screens 42.

These screens are located in the path of lliquid passing from the chamber 12 to the chamber 1,3 and provide for the separation of extraneous matter from the liquid. The

A chamber 41 is provided with an outlet opening 43 which is spaced upwardly from the bottom of the chamber. Thus liquid entering the chamber 41 will be filtered by ,the screens 42 and any dirt or sediment .passing through these screens will gravitate .to the bottom of the chamber 41 while the liquid will pass out through the opening 43. The Aliquid before passing outward through the discharge port provided in the nip-ple 19 must first reach the height of the inner en d of the extension 2O of the `nipple so that further settling will be provided for. Any sediment collecting in `the bottom of the chambers 13 and 41 may be readily removed by detalling the tank from the top 14.

" During the operation of the engine suction through the passage 24 will drawy fuel through` the Supply tank from the nipple 18,

the weight of the float 39 upon the ange 38 holdingV the valve member 29 upon the seat 2,8. A-vacuum or partial vacuum will thus be formed within the chamber 112 which will act te hold the valve 40 closed. Fluid will thus be collected within the inlet chamber 12 so that .the float 39 will rise and engage the arms 36,- upward movement of the float lifting `the valve member 29 from the seat 38 and causing the said member to engage the seat 27. This change of position of the valve member is assisted by means of springs 44 which connect the pins 45 extending from the members 33, the said springs acting to 'snap the arms 32 over center and hold the valve in position. Suction will thusbe cut olf and at the same time vacuum within the chamber 12 will be relieved so that the valve 40 will open and the liquid pass out of the chamber 12 into the chamber 13 through the chamber 4l.. As the chamber 12 empties the float :39 will .descend until it .engages the flange 38, the weight of the float pulling the sleeve 39 downward and snapping the arms 32 over center so as to engage the valve member 29 with the seat 28.

A deflecting chute or baille 46 is located beneath the nipple 18 so that force of the liquid entering the tank will not effect the operation of the valve member 29.

While the invention is shown and described as a fuel feed tank it is capable of various other uses. VFor example it can be used as a combined oil filter and pump by connecting the nipple 18 with the oil =reservoir of the engine and connecting the nipples 19 `and 24 respectively with oil distributing means and with the intake manifold of the engi-ne.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved :to make such changes as properly fall within the Vscope of the appended claims.

valve common to both of said seats, said suction passage having openings provided 1n its walls upon opposite' sides of the valve seats, stems extending from the valve through said openings, spring resisted means engaging the stems to yieldingly hold the va ve against movement, arms pivotally secured to the post and operatively associated with the stems, means for yieldingly holding the arms against movement and float actuated means for operating the arms.

3. A vacuum feed tank comprising a casing, means dividing the casing into an inlet chamber and a discharge chamber, a fluid inlet for the inlet chamber, a fluid outlet for the discharge chamber, a vacuum controlled valve providing communication between the inlet and discharge chambers, a guide post within the inlet chamber, a passage extending inwardly from one end of the post and providing a suction passage adapted for communication witha source of suction, a vacuum relief port communicating with the suction passage, spaced valve seats within the suction passage between the outer end of the latter and the vacuum relief port, a valve common to both of said seats, said suction passage having openings provided in its walls ,uponv opposite sides of the valve seats, stems extending from the valve through said openings, sprin resisted means engaging the stems to yiel ingly hold the valve against movement, arms ivotally secured to the post and operative y associated with the stems, means for yieldingly holding the arms against movement, a sleeve slidable upon the post, means operatively connecting the sleeve and arms whereby movement of the sleeve will actuate the arms to control the position of the valve anda oat slidable upon the sleeve for moving the latter.

4. In a vacuum feed tank, an outlet chamber, a discharge chamber, means to control the passage of liquid from the outlet to the discharge chamber, a receiving chamber within the discharge chamber, means to direct the flow ofliquid from the discharge chamber into the receiving chamber and said receiving chamber having an opening therein spaced upwardly from its bottom to provide a discharge port into the outlet chamber.
